Suspension: what's the weak link in the stock setup?

Brembo setup, getting a lot of boat float at freeway speeds (sorry for the broken record, but ... I'm used to german car brittle-ass suspensions), enough that my wife is starting to get car sick on longer trips.

My first inclination is that the dampers are too soft but wanted to see if anyone knows for sure before I go buying parts.

How's the Ford motorsport stuff stack up against brembo stock? Lot stiffer, just a little bit stiffer?

I actually find the softer ride pleasant compared to my previous cars (or the wife's Q7 with air suspension that feels like it's filled with rocks) but every now and then you hit a expansion joint just right and the whole car floats around and bounces a couple of times before settling. That's what I'm looking to get rid of.

From what I gather, if I swap the suspension for something with shorter springs I'll need a new adjustable panhard bar? And shops should know how to adjust it yeah?

Stiffen it up and she's bound to complain about her back hurting.
I'd say if you are looking to stiffen the suspension lower it the same way others have done.

From what I've heard, getting street shocks n struts will greatly improve the suspension.

But need some indication of how much stiffer it'll be. To me the brembo susp is pillow soft, but they might've recalibrated for the convertible too?

I'm not. But, like I said, her daily driver is a Q7 and that thing is brutally stiff compared to my car.

Shocks and struts are a day and night difference on these cars. They might be THE "weak link". But I hesitate to make a suggestion if you think your wife's car is "brutally stiff" from the factory.

To me, adjustable struts and shocks along with springs that don't have a crazy high rate, are an excellent addition to the car. Sway bars are a nice way to improve cornering without going crazy with the spring rate.

The upper and lower control arms are also a weak link on these cars. Even our street style control arms are a huge improvement over the factory control arms. (our Pro Series are really nice, but they increase NVH, so they're not as common for the street-going crowd) 2011 Ford Mustang GT V6 Chrome Moly Street Upper & Lower Control Arm Package - UPR Products

They have a video out where they test the GT vs the new M3 and the driver said afterwards that the dampening felt soft on the Mustang. Other then the dampening he didn't have much neagtive to say about it.

You can look at the mod's I've done at the moment the rear of the car is very tight and no wheel hop. It just feels solid and I haven't added sway bars, shocks or springs yet.

I'm torn between going with springs, strut/shock combo with sway bars or going for the Steeda Coil over setup with sway bars.

Wasn't aware you could get Brembos with the convertible.

Anyway, struts control the "pogoing" effect you're describing, and many people have complained that they're too soft. If you replace the struts (and rear shocks) with some Tokicos or Konis I think you'll find that your ride's a little better.
